London Joinery Services explains the process of repair

 

If you love the period charm and heritage innate in your wooden sliding sash windows but hate the draughts, rattles, rot and heat loss that can also be part and parcel with an older property then you need help from the experts. With over many years’ experience repairing windows across the London, 

you can trust London Joinery Services.

​

The replacement of sash windows is, in many cases, completely unnecessary. There are very few instances where damage and decay cannot be repaired using the right knowledge and tools. Repair work will depend on the damage. Decaying timber, broken sash cords, damaged pulleys and broken glass, will all need replacing.

 

Traditional timber sash windows are an essential feature of a period buildings character. Therefore it is vital to retain them, not only because of the aesthetic appeal, but because they add value to your property. Also known as a sliding sash or vertical sliders, they rely on a weighted system that allows the heavy sashes to lift and fall with ease. In order for the sashes to move in the box and operate smoothly, there is a 3mm gap between the sash and the frame which is often the cause of draughts, rattles, dust and rain ingress and heat loss. 

​

Our service focuses firstly on window repair and secondly on upgrading their performance.

avoid of re-glazing existing windows

Many want to know if they can have new double-glazed units fitted into their existing timber sashes. The advice is to be careful — these windows were never designed to take two panes of glass, each thicker & heavier than the original.

​

The glazing bars in old sash windows are often not deep enough to take sealed double-glazed units, which ultimately leads to premature misting. we can do but we not recommended !!

​

Another option is to have new sashes made to fit your existing frames and to match the originals. London Joinery Services uses new slim glazing units and traditional methods of carpentry for an authentic look.
